Aperture screw thread shrinkage pool facing forward is offered in the middle part of wall；Guide blot runs through tapped through hole, and the tail end of guide blot is screwed in spiral shell
In line shrinkage pool；It is respectively opened up in the middle part of the top edge of two brake pads there are one assembling through hole, and two brake pads pass through two respectively
Through hole slidable fit is assembled on guide blot；Two end faces of the front of two brake pads respectively with brake disc separably connect
It touches；Four piston end surfaces of the back side left part and back side right part of two brake pads respectively with four caliper are fixed；Resetting spring
It is sheathed on guide blot, and the both ends of resetting spring are fixed with the front of two brake pads respectively；
The inward flange of brake disc offers several arc-shaped gap；Each arc-shaped gap is along the circumferentially equidistant of brake disc
Arrangement；The end face of brake disc offers several columns circular through hole；Each column circular through hole is along the radially equidistant arrangement of brake disc；Respectively
Row circular through hole is staggered along the circumferentially equidistant of brake disc；Two end faces of brake disc offer several shaped form ditches
Slot；The both ends of each shaped form groove respectively penetrate through the medial surface and lateral surface of brake disc；The braking of each shaped form groove edge
The circumferentially equidistant arrangement of disk；The front of two brake pads is equipped with several columns hemispherical convex closure；Each column hemispherical convex closure is along system
The radially equidistant arrangement of Moving plate；Circumferentially equidistant arrangement of each row hemispherical convex closure along brake disc.
Specific work process is as follows：When the brake is applied, four pistons of four caliper promote two brake pads to carry out
It moves toward one another, thus on the one hand so that the front of two brake pads is contacted with two end faces of brake disc, on the other hand
So that compressive deformation occurs for resetting spring.At this point, the hemispherical convex closure on two brake pads is tied with braking side surface and its end face
Powerful frictional force is generated between structure (i.e. shaped form groove), so that the rotating speed of brake disc reduces, so that equation
The wheel hub of racing car and the rotating speed of core wheel reduce, and then realize the braking of equation motorcycle race.After end of braking, in pushing away for resetting spring
Under dynamic, four pistons of two brake pads and four caliper return to original position.In above process, the effect of circular through hole is scattered
Heat.
Based on the above process, compared with existing braking system, a kind of equation with biomimetic features of the present invention
Racing car braking system is based on bionic principle and (imitates the non-smooth surface of the animals such as shell, pangolin, desert lizard, the Non-smooth surface
Surface has good wearability) and brand new, the braking of equation motorcycle race is realized, thus possesses following advantage：Its
One, the brake force that the present invention generates is larger, therefore its brake efficiency is stronger, thus significantly improves when equation motorcycle race is competed
Cornering ability.Second, the present invention is during the work time, the wear extent of brake disc is smaller, therefore its service life is longer, thus
Equally significantly improve cornering ability during equation motorcycle race match.Experiments have shown that the friction system of the present invention at the working temperature
Number up to 0.41, low wear rate to 1.39*10-7cm3·(N·m)-1。
The present invention is rational in infrastructure, ingenious in design, efficiently solve existing brake system efficiency is poor, service life compared with
The problem of short, competes suitable for equation motorcycle race.
